2. Description of the Related Art Dietary fiber has recently attracted attention as a health food material. Dietary fiber is roughly classified into two types.
One of them is insoluble dietary fiber, whose primary effects are increased stool volume, reduced transit time of intestinal contents, intestinal pressure,
There is a decrease in abdominal pressure, and as a result, it is said to be effective in preventing and treating various colorectal diseases such as constipation and colorectal cancer. The other is
It is a water-soluble dietary fiber, and its primary effects are activation of gastrointestinal tract activity, decreased digestion and absorption of dietary components, reduced bile acids circulating in the enteroliver, and changes in the type and metabolism of intestinal bacteria. It is said to be effective in preventing and treating constipation, colorectal disease, obesity, diabetes, hyperlipidemia and the like.

[0003] The insoluble dietary fiber has drawbacks due to its physicochemical properties, such as insolubility in water, no matter how fine it is made, and greatly impairing the texture in the mouth. Therefore, attempts have been made to extract water-soluble dietary fiber having no such defects from many vegetable fiber raw materials.

By the way, barley contains β- (1,3) (1,4) -D as water-soluble dietary fiber, in addition to arabinoxylan, which is a hemicellulose component contained in the hull of wheat or the like.
-A great feature is that it contains a large amount of glucan. It is considered that the physiological action of β-glucan has a particularly strong effect of suppressing serum cholesterol and blood sugar level elevation by decreasing serum insulin concentration. However, in recent years, our dietary habits have been more similar to those of Western countries than before,
It is said that the intake of plant fiber is greatly reduced.
The National Nutrition Survey also reveals a decrease in dietary fiber intake from cereals, arguing that a decrease in barley intake is attributable to a lack of dietary fiber intake. Some are experts. Therefore, it is necessary to separate and purify a water-soluble dietary fiber having a specific physiological action, that is, β-glucan derived from barley bran, from the bran, which is a by-product of barley barley, both industrially and in terms of effective use of the by-product. ing.

[0006] However, when the β-glucan is extracted from barley bran, when the above-mentioned pressurized hot water treatment is carried out, the starch is remarkably gelatinized and has a high viscosity, which greatly hinders the extraction operation. In addition, in the case of alkali extraction, problems such as operations such as neutralization of the extract and treatment of the extraction residue occur. Also, α-
Although the viscosity decreases when treated with amylase, the production and contamination of dextrin without human digestive enzyme resistance is remarkable, and the resulting extract has a reduced content of the target β-glucan. Furthermore, if the starch is removed from barley bran in advance by physical treatment such as sieving, water washing, or chemical treatment such as enzyme treatment, the extract obtained therefrom is:
β-glucan content is low. The reason is that β
-It was thought that the reason was that glucan was present more in the starch fraction and the aleurone layer.

In the present invention, barley bran is used as an extraction raw material. As shown in Table 1, the barley raw materials are roughly classified into two types: bark and bark, each of which has stickiness and stickiness. Skinning is further classified into small grains and large grains. Therefore, although sticky barley is preferably used as a raw material for extracting β-glucan, bare wheat is more preferably used in view of the supply of raw materials.

[Table 2] The selected barley is rough-milled with a grinding mill to remove the outer skin (husk, pericarp, seed coat) and some aleurone layers. This step is usually performed to a milling yield of 82%. The bran generated at this time is referred to as rough milling bran. This bran is not suitable as an extraction raw material because of its coarse particle size and low β-glucan content.

The method for extracting β-glucan from barley bran in the present invention is as follows: 100 parts by weight of barley bran, 500 to 1500 parts by weight of hot water at 80 to 95 ° C., and heat-resistant α-amylase per 1 kg of raw material , 3,000-30,000
It is desirable to add a unit and extract while stirring at 80 ° C to 90 ° C for 1 to 12 hours. Thereafter, 400 to 4,000 units of glucoamylase are added to 1 kg of the raw material to digest the solubilized digestible dextrin, and
It is preferable to digest while stirring at 0 ° C to 60 ° C for 3 to 24 hours. As described above, digestive dextrin contained in components solubilized from starchy barley bran is decomposed into monosaccharides only by simple operations of extraction and reaction with addition of enzymes, and as a result, the solubilized fraction The polysaccharide contained therein has a high content of indigestible β-glucan. At the same time, since the viscosity is extremely reduced, there is an advantage that the operation of solid-liquid separation becomes easy.

According to the present invention, when β-glucan is extracted from barley bran, when starch is subjected to hot water treatment under pressure, gelatinization of the starch is remarkable, resulting in a high viscosity, which greatly hinders the extraction operation. In addition, in the case of alkali extraction, problems such as operations such as neutralization of the extract and treatment of the extraction residue occur. In addition, although the viscosity is reduced only by treatment with α-amylase, the production and contamination of dextrins that are not resistant to human digestive enzymes are remarkable, and the resulting extract has a reduced content of the target β-glucan. I will. Furthermore, when starchy matter is previously removed from barley bran by physical treatment such as sieving or washing, or chemical treatment such as enzyme treatment, the extract obtained therefrom has a low β-glucan content. This was thought to be because β-glucan was more present in the starch fraction and the aleurone layer.
